[PATCH 1/4] microblaze: fix 'FORCE prerequisite is missing' warning

[Masahiro Yamada]

If you add foo.dtb into the arch/microblaze/boot/dts/ directory and
run 'make simpleImage.foo', you will observe the following warning:

  arch/microblaze/boot/dts/Makefile:15: FORCE prerequisite is missing

Without FORCE, if_changed cannot detect the command line changes.
